CLIFFORD J. GELVIN AND JOHN C. CLARK, OF NEW RICHMOND, OHIO.

MUSIC-LEAF TURNER.

Application filed May 17, 1913.

To all whom it may concern Be it known that we, CLIFFORD J. GELVIN and JOHN C. CLARK, citizens of the United States, residing at New Richmond, in the county of Glermont and State of Ohio, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

The invention relates to music, and more particularly to devices for turning the leaves of music, and has for an object to provide a device preferably adapted for use in connection with organs and pianos or other musical instruments, for turning the pages of sheet music readily and quickly.

The invention embodies, among other features, a device of simple and durable construction and which can be easily supported upon a musical instrument and which is adapted to be actuated by the operator to turn a page of sheet music when the operator finishes playing one side of the page and desires to uncover the other side thereof, the device being arranged within easy reach of the operator so that the page will be quickly and readily turned without inconveniencing the operator and necessitating a long pause while the sheet of music is being turned.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure l is a front elevation of the device, the same being shown as supported on the front of a piano; Fig. 2 is a plan view; Fig. 3 is a vertical sectional view taken on the line 3-3 in Fig. 2; Fig. 4 is a vertical transverse sectional view taken on the line 1-4; in Fig. 1; and Fig. 5 is a perspective view of one of the turning members.

Referring more particularly to the views, we provide a base 10 which is adapted to be supported in any convenient manner on a stand or musical instrument such as a piano 11, the said base carrying a sheet music supporting member 12 consisting of an upright 13 having rigid connection with the base 10 and a clamping member 141, similar in shape to the upright and carrying a pin 15 passing loosely through the upright 13, the said pin being provided with a head 16, a contractile helical spring 17 being arranged to encircle the pin and interposed between the head Specification of Letters Patent.

and upright to bear against the upright and hold the inner face of the clamping member against the inner face of the upright 13. A handle 18 includes a shank 19 which passes loosely through the upright 13 and has the inner end rigid in the clamping member 14, so that when pressure is exerted on the handle 18 the upright 13 and the clamping member 14 will be moved apart to permit of inserting a book of music 20 between the upright and clamping member, after which the pressure on the handle 18 is released, thus causing the clamping member to move toward the upright, by the action of the spring 17, so that the book of music 20 will be clamped between the upright and clamping member in a manner which will permit of readily turning the pages thereof.

Projecting forwardly from the base 10 are a plurality of supporting members 21 and 22, the said supporting members carrying turning members 23 and 24 respectively. Each of the turning members consists of a rod 25 having pivotal connection with one of the supporting members 21 and 22, and having mounted to swing adjacent the free end thereof a suitable finger 26 normally projecting upwardly and at right angles to the rod 25. Extending from the under side of the rod 25 is a pin 27, to which is connected a cord 28 having its other end connected to a contractile spring 29 secured to the base 10, the said pin 27 being spaced a slight distance from the point of pivotal connection of the finger 26 with one of the supporting members 21 and 22, as mentioned heretofore.

Mounted to swing on the base 10 are a plurality of actuating members 30, carrying knobs 31 on their outer ends and having their inner ends adapted to bear against the rear edges of the rods of the turning members 22 and 24 and between the points of pivotal connection of the turning members with the supporting members 21 and 23 and the points of connection of the cord 28 with the rods of the turning members.

Now it should be particularly noted that when a book of music is supported on the member 12, the turning members 23 and 2% are arranged so that one of the fingers 26 of one of the turning members will lie beneath one of the pages of the book and the finger of the other turning member will lie beneath the next page of the book so that the front face of the first page will be uncovered, thus permitting the player or operator to readily read the music thereon. Now it will be seen that when the turning members are in the position mentioned the pull exerted by the springs 29 upon the turning members will have no efiect inasmuch as the points of pivotal connection of the turning members with the supporting members 22 and 2% are offset from the line of pull between the points of connection of the cord 28 with the turning members and with the springs 29 so that the said springs, when the turning members are in initial position as mentioned, will tend to hold the turning members against the adj acent pages which they are adapted to turn, thus preventing the turning of the pages for which the turning members are provided. If, however, the operator desires to turn the first page of the book of music, he exerts a pressure against the knob 31 of the first actuating member 30 so that the inner end of the actuating member will actuate the uppermost turning member between the point of pivotal connection of the turning member with the supporting member 21 and the point of connection of the cord 28 with the turning member, thus swinging the turning member forwardly so that the pull on the cord will be in front of the point of pivotal connection of the turning member with the supporting member 21 and it will then be apparent that the pressure of the spring 29 having connection with the turning member 23 through the medium of the cord 28, will exert a pull on the turning member, thus swinging the same forwardly and then swinging the same against the base 10 adjacent the spring 29. Now inasmuch as the finger 26 of the turning member 23 previously was placed beneath the page to be turned, it will be apparent that the swinging movement of the turning member 23 will turn the page of the book of music to expose the rear face thereof and the front face of the neXt page, beneath which the finger of the second turning member 24; lies, and when the operator has finished playing the music which has been uncovered by the turning of the first page, he presses against the second actuating member which, operating in the same manner as the first actuating member, moves the second turning member into position to be acted upon by the spring thereof so that the second turning member will be swung into substantially the same position as the first turning member has been swung, thus turning the second sheet of the book of music.

It will be understood that as many turning members as are desirable may be provided on a device such as described, and it will be apparent that our device is of a simple and durable construction, can be readily manufactured at a small cost and does not take up much space on the instrument, while at the same time it not only provides for the turning of the pages of a book of music but also supports the book of music in a position which permits of the operator readily reading the notes.

Having thus described our invention, we claim:

In a music leaf turner, the combination with a base, of an upright, a clamping member on the upright for clamping a book of music thereto, a turning member mounted to swing on the base and including a rod and a finger projecting laterally therefrom, a depending pin adjacent the inner end of the turning member, a spring having one end connected to the base, a cord connected with the spring and having connection with the said depending pin of the turning member, said turning member being normally arranged so that the pin connecting with the cord will lie beyond the line of pull of the said spring, with the said turning member adapted to be swung by the action of the spring when the pin thereof, connecting with the cord, is brought into the line of pull of the spring, and an actuating member mounted to swing on the base and having an upwardly extending offset portion engaging the turn ing member between the depending pin and the point of connection of the turning member with the base, said actuating member, when operated, being adapted to swing the turning member into a position whereby the pin will be brought into the line of pull of the spring so that the full action of the spring, exerted on the turning member, will swing the same from one side of the upright to the other side thereof, said turning member having connection with one of the sheets of the book of music to carry the latter with it in its turning operation.

In testimony whereof we afiiX our signatures in presence of two witnesses.
